NB7N017M

NB7N017M 3.3 V SiGe 8‐Bit Dual Modulus Programmable Divider/Prescaler with CML Outputs Description The NB7N017M is a high speed 8-bit dual modulus programmable divider/prescaler with 16 mA CML outputs capable of switching at input frequencies greater than 3.5 GHz. The CML output structure contains internal 50 W source termination resistor to VCC. The device generates 400 mV output amplitude with 50 W receiver resistor to VCC. This I/O structure enables easy implementation of the NB7N017M in 50 W systems. The differential inputs contain 50 W termination resistors to VT pads and all differential inputs accept RSECL, ECL, LVDS, LVCMOS, LVTTL, and CML. Internally, the NB7N017M uses a > 3.5 GHz 8-bit programmable down counter. A select pin, SEL, is used to select between two words, Pa[0:7] and Pb[0:7], that are stored in REGa and REGb respectively. Two parallel load pins, PLa and PLb, are used to load the level triggered programming registers, REGa and REGb, respectively. A differentia...
